NOTE1: USB UART is partitioned for non-secure world. Secure world still can share
it with limit that its interrupt cannot use in secure world.
NOTE2: In secure world, USB UART is only for Greentea and STDIO. Developers shouldn't
use it for other purposes.
Support secure/non-secure combined build for non-PSA target:
1. In secure post-build, deliver built secure image to TARGET_NU_PREBUILD_SECURE
directory which is to combine later.
2. In non-secure post-build, merge non-secure image with secure image saved in
TARGET_NU_PREBUILD_SECURE directory.
3. In non-secure post-build, user can also drop pre-built secure image saved in
TARGET_NU_PREBUILD_SECURE directory and provide its own by adding the line below
in mbed_app.json:
"target.extra_labels_remove": ["NU_PREBUILD_SECURE"]
1. Create a private target name NU_PFM_M2351_CM which stands for the
NuMaker-PFM-M2351 board and is to be extended.
2. NU_PFM_M2351_NPSA_S/NS target names for non-PSA secure/non-secure targets
respectively.
3. The original target name NUMAKER_PFM_M2351 is recycled and cannot be used.
Use NU_PFM_M2351_S/NS for non-PSA secure/non-secure targets instead.
NOTE: Target name doesn't follow the rule below because online database has
limit of max 20 chars:
NUMAKER_PFM_M2351_PSA/NOPSA_S/NS
Instead, it has the rule:
NU_PFM_M2351_[NPSA_]S/NS
NU_PFM_M2351_S/NS for PSA targets. This is to be consistent with current
PSA target naming. So the resolved target names are:
NU_PFM_M2351_S : PSA secure target
NU_PFM_M2351_NS : PSA non-secure target
NU_PFM_M2351_NPSA_S : Non-PSA secure target
NU_PFM_M2351_NPSA_NS : Non-PSA non-secure target
We should not block in case the UART is busy transmitting. The
API has been updated to check the status of all UART's and return
1 in case any of them is busy transmitting.

The code checks if any of the UART's is still transmitting.
If so then prevent from entering deepsleep
